Average price of these 3 knives?

[beretta40ss]

1. 520 Presidio Pardue/straight edge satin finish
2. 420 Resistor/straight edge satin finish
3. 710 M&W/straight edge satin finish

I havn't heard a whole lot about the Presidio. Does anyone know much about this knife and its pros and cons. Thanks

The handle is a bit thick, but it seems to be a favorite. www.newgraham.com has the better prices
